Sensor subassembly for a vehicle and device for measuring rotational movements of a wheel bearing
First Claim
1. A sensor subassembly configured to be mounted on a stationary part of a bearing for a vehicle, the sensor subassembly comprising:
- a retaining bush configured to be received within the stationary part;
at least one sensor unit arranged in a cap-shaped plastic part, the cap-shaped plastic part carried by the retaining bush and configured to seal the retaining bush at an end; and
a resilient sealing and compensating element pressed in between the cap-shaped plastic part and the retaining bush in a first sealing region so as to seal a first leakage path such that the cap-shaped plastic part in conjunction with the sealing and compensating element tightly seals the retaining bush at the end,wherein the sealing and compensating element is inserted in the first sealing region such that the sealing and compensating element is compressed only between a first sealing surface of the cap shaped plastic part and a second sealing surface of the retaining bush,wherein the retaining bush at a second sealing region is compressed via a third sealing surface with a fourth sealing surface on a stationary part of a wheel bearing to at least partially seal a second leakage path, andwherein the sealing and compensating element is arranged only in the first leakage path and is spaced apart from the second leakage path.

Abstract
A sensor subassembly for a vehicle has at least one sensor unit arranged in a cap-shaped plastic part. The cap-shaped plastic part is carried by a retaining bush and seals off the retaining bush at one end. An associated device is configured to measure rotational movement of a wheel bearing. A resilient sealing and compensating element in pressed in between the-shaped plastic part and the retaining bush, in a first sealing area for sealing off a first leakage path, so that the cap-like plastic part, in conjunction with the sealing and compensating element, seals off the retaining bush tightly at one end.

9. A device for measuring rotational movements of a wheel bearing for a vehicle comprising:
-
at least one signal emitter arranged on a rotating part of the wheel bearing; and one stationary sensor subassembly comprising; at least one sensor unit arranged in a cap-shaped plastic part, wherein the cap-shaped plastic part is carried by a retaining bush and covers the wheel bearing; and a resilient sealing and compensating element pressed in between the cap-shaped plastic part and the retaining bush in a first sealing region so as to seal a first leakage path such that the cap-shaped plastic part in conjunction with the sealing and compensating element tightly seals the retaining bush at a first end, wherein the sealing and compensating element is inserted in the first sealing region such that the sealing and compensating element is compressed only between a first sealing surface of the cap-shaped plastic part and a second sealing surface of the retaining bush, wherein the retaining bush at a second sealing region is compressed via a third sealing surface with a fourth sealing surface on a stationary part of the wheel bearing to at least partially seal a second leakage path, and wherein the sealing and compensating element is arranged in the first leakage path and spaced apart from the second leakage path. - View Dependent Claims (10)
