Abstract

A handlebar grip (10) for a throttle twist grip (1) is arranged on a handlebar tube of a vehicle and is intended for actuating an actuator which determines the fuel supply for an internal combustion engine of the vehicle). The handlebar grip (10) has a spring engagement section (12) for engagement of a restoring spring (20). The spring engagement section (12) is formed in an outer region of the handlebar grip (10) in the longitudinal direction of the handlebar grip (10).

Claims

1. Handlebar grip for a throttle twist grip arranged on a handlebar tube of a vehicle and intended for actuating an actuator which determines the fuel supply for an internal combustion engine of the vehicle,

the handlebar grip having a spring engagement section for engagement of a restoring spring,

wherein the spring engagement section is formed in an outer region of the handlebar grip in a longitudinal direction of the handlebar grip.

2. Handlebar grip according to claim 1, furthermore having a sensor holding section for holding a sensor for detecting the rotational position of the handlebar grip, the spring engagement section being formed in an inner region of the handlebar grip in the longitudinal direction of the handlebar grip.

3. Handlebar grip according to claim 2, wherein the spring engagement section and the sensor holding section are formed in opposite end regions of the handlebar grip, relative to the longitudinal direction of the handlebar grip.

4. Handlebar grip according to claim 1, furthermore having a mounting section for mounting the handlebar grip on the handlebar so as to be rotatable about the axis of the handlebar in the grip region, the spring engagement section being formed in an inner region of the handlebar grip in the longitudinal direction of the handlebar grip.

5. Handlebar grip according to claim 4, wherein the spring engagement section and the mounting section are formed on opposite sides of the handlebar grip, relative to the longitudinal direction of the handlebar grip.

6. Handlebar grip according to claim 4, furthermore having a sensor holding section for holding a sensor for detecting the rotational position of the handlebar grip, wherein the mounting section is formed outside the sensor holding section, relative to the longitudinal direction of the handlebar grip.

7. Throttle twist grip having a handlebar grip according to claim 1.

8. Throttle twist grip according to claim 7, furthermore having at least one restoring spring.

9. Throttle twist grip according to claim 8, wherein the restoring spring is in the form of a torsion spring.

10. Throttle twist grip according to claim 9, wherein the torsion spring is in the form of a helical spring.

11. Throttle twist grip according to claim 9, wherein the torsion spring is in the form of a torsion bar.

12. Throttle twist grip according to claim 7, furthermore having a spring housing.

13. Throttle twist grip according to claim 12, wherein the spring housing is fixed on the spring engagement section of the handlebar grip to be rotatable about the longitudinal axis of the throttle grip, by a screw and/or bolt connection.

14. Throttle twist grip according to claim 12, wherein the spring housing has an external diameter which substantially corresponds to the internal diameter of the handlebar grip.

15. Throttle twist grip according to claim 12, wherein the spring housing has an engagement section for engaging a correspondingly formed engagement section of a handlebar tube in a nonrotatable manner.

16. Throttle twist grip according to claim 15, wherein the engagement section of the spring housing is formed on an inside of the spring housing.

17. Throttle twist grip according to claim 15, wherein the engagement section of the spring housing has ribs for accommodation in corresponding recesses provided on the handlebar tube.

18. Throttle twist grip according to claim 12, furthermore having a handlebar weight, the spring housing being integrated in the handlebar weight.

19. Throttle twist grip according to claim 18, wherein the handlebar weight is formed to be fixed in a nonrotatable manner on a handlebar tube by a screw and/or bolt connection.

20. Throttle twist grip according to claim 12, wherein the spring housing is integrated in a region of the handlebar tube which is an outer region relative to the handlebar.

21. Throttle twist grip according to claim 12, wherein the spring housing is formed to be inserted into a region of a handlebar tube which is an outer region relative to the handlebar.

22. Throttle twist grip according to claim 12, wherein the restoring spring has a handlebar grip engagement section for engagement in the handlebar grip and a spring housing engagement section for engagement in the spring housing.

23. Throttle twist grip according to claim 12, wherein the sensor is in the form of an angle sensor in the form of a contactless and/or non-contact angle sensor and/or potentiometric angle sensor and/or in the form of a Hall sensor, in the form of a Hall-effect pick-up, in the form of a Hall controller, in the form of a gyroscopic sensor, in the form of a piezo sensor, in the form of a position sensor in the form of a magnetostrictive position sensor, in the form of a shaft encoder in the form of a magnetic incremental encoder, in the form of a magnetic angle sensor in the form of a magnetic scale sensor, in the form of a cable extension sensor, in the form of an inductive sensor, in the form of a capacitive sensor and/or in the form of an optoelectronic angle sensor.

24. Throttle twist grip according to claim 12, wherein at least one pressure sensor is provided for measuring the pressure exerted by the restoring spring.

25. Throttle twist grip according to claim 24, wherein the at least one pressure sensor is formed and arranged for receiving an end of the restoring spring.
