Abstract

A vehicle, in particular an agricultural tractor, is disclosed with a vehicle chassis, which is formed at least partly from two laterally spaced side members (1, 2) with C-shaped profile, comprising a vertical bar (1a, 2a) and two horizontal flanges (1b, 2b) and containing hydraulic lines in the space between the flanges, and with a radiator sub-assembly (5), fitted to the vehicle chassis, which consists of a carrier plate (6) fitted to the side members and several oil coolers (8, 9) supported by the carrier plate. In order to improve the routing of the hydraulic lines to the oil coolers and to provide unhindered assembly and simple subsequent maintenance, it is proposed that the open sides of the C-profile of the side members (1, 2) should point to the vehicle exterior, that at least one subsection (6b) of the carrier plate (6) extends into the region between the side members (1, 2) and that ducts (6g, 6h, 6j, 6k), connected to the oil coolers (8, 9) are integrated into the at least one subsection (6b) of the carrier plate (6) and flow into lateral ports (6l, 6m, 6n, 6p) turned towards the vertical bars (1a, 2a) and can be connected through recesses (1c, 2c) in the bars (1a, 2a) to hydraulic lines (12, 13, 14, 15) laid between the flanges (1b, 2b).

Claims

1. A utility vehicle, in particular an agricultural tractor, with a vehicle chassis, which is formed at least partly from two laterally spaced side members with a C-shaped profile, each side member having a vertical bar and two horizontal flanges and containing hydraulic lines in the space between the flanges, and with a radiator sub-assembly, fitted to the vehicle chassis, which consists of a carrier plate fitted to the side members and several oil coolers supported by the carrier plate, wherein the open sides of the C-profile of the side members point to the vehicle exterior, at least one subsection of the carrier plate extends into the region between the side members and ducts connected to the oil coolers are integrated into the at least one subsection of the carrier plate and flow into lateral ports turned towards the side member vertical bars and are connected through recesses in the bars to hydraulic lines laid between the horizontal flanges.

2. A vehicle according to claim 1 in which the at least one subsection of the carrier plate extends close to the bars.

3. A vehicle according to claim 1 in which the carrier plate is formed as a casting.

4. A vehicle according to claim 1 in which the carrier plate is welded or bolted onto the side members.

5. A vehicle according to claim 1 in which further ducts are provided in carrier plate which are connected to hydraulic lines laid between the flanges, these further ducts being are connected to a valve block arranged on the carrier plate through which pressurised hydraulic fluid can be provided to operate attachments carried on the vehicle.
