Abstract

In an end take-off steering gear, tie rods 22 are mounted on a bracket 24 fixed to the end 26 of the steering gear rack 20 which is approximately at the centre line of the vehicle. Between the ends 26 of the rack and the other side of the vehicle, a steering damper 36 is mounted in line with the rack 20. <IMAGE>

Description

SPECIFICATION Steering gear arrangement This invention relates to a steering gear arrangement for use in a motor vehicle.
Current trends in motor vehicles design are towards efficient packaging of vehicle components, particularly the mechanical components. In many cases it is desirable to arrange the steering gear rack in a position other than directly between the wheels to be steered, and to make this possible tie rods are used to transmit the motion of the rack to the wheels.
It has been proposed to use what is known as an "end take-off" steering gear. Such a gear has a rack which extends over only about half the width of the vehicle, such that it has an end in the region of the vehicle centre line. Tie rods are then connected between this end and the wheels to be steered.
According to the present invention, there is provided a steering gear arrangement comprising an end take-off steering gear mounted between one side of the vehicle and the vehicle centre line, and a steering damper arranged between a mounting point on the other side of the vehicle and the end of the steering gear and generally in line with the steering gear.
This arrangement makes for efficient packaging of the steering damper when used in conjunction with an end take-off steering gear. The arrangement makes more efficient use of space than the conventional arrangement of a steering damper along-side the steering gear.
The arrangement also gives benefits in reducing the modifications necessary to produce both left hand and right hand versions of the same vehicle model, where the positions of the steering gear and the steering damper have to be reversed.
Furthermore, the "in-line" arrangement can result in less lost motion between the components than a conventional "alongside" arrangement.
The invention will now be further described, by way of example, with reference to the accompanying drawing which is a schematic view of a steering gear arrangement in accordance with the invention.
The parts of the vehicle bodywork shown in the drawing are two side apron panels 10 and the dash panel 12. The steering gear 14 is mounted by means of bearing blocks 16 to the rear of the dash panel 12.
The steering gear has a conventional pinion 18 which engages with a rack 20.
Steering tie rods 22 are connected to a bracket 24 which is fixed to the end 26 of the rack 20. It will be noted that the bracket 24 is arranged so that the ends of the tie rods are equidistant from the centre line 28.
When the steering wheel is turned, the pinion 18 turns and causes the rack 20 to reciprocate. This moves the bracket 24 and causes the tie rods 22 to move to turn the wheels of the vehicle.
The end 26 of the rack 20 also has a lug 30 which has a hole through it. This end is engaged by a fork 32 on the end of the piston 34 of a steering damper 36. The other end of the steering damper is fixed at 38 to a bracket 40 mounted on the side apron panel 10. The damper 36 thus is able to damp movement of the steering rack 20.
In the embodiment shown, a bracket 40a is provided on the left hand side side apron 10, and it will be clear from the drawing that on the left hand drive car shown the damper occupies the space where the steering gear will be mounted for a right hand drive car. Very few modifications are therefore necessary in changing from production of left hand drive to right hand drive vehicles.
1. A steering gear arrangement comprising an end take-off steering gear mounted between one side of a vehicle and the vehicle centre line, and a steering damper arranged between a mounting point on the other side of the vehicle and the end of the steering gear and generally in line with the steering gear.
2. A vehicle including a steering gear arrangement as claimed in Claim 1, wherein a mounting point for the steering damper is provided at both sides of the vehicle, to accommodate the steering damper both in its position for a right hand drive vehicle as well as for a left hand drive vehicle.
3. A steering gear arrangement substantially as herein described with reference to the accompanying drawing.
