RU128592U1 - SUB-FRAME OF INDEPENDENT SUSPENSION OF THE FRONT WHEELS OF THE VEHICLE - Google Patents

Abstract

A subframe for independent suspension of the front wheels of the vehicle, comprising a cross member, brackets for securing the cross member, bushings of the axles of the lower suspension arms, upper bearings of the suspension springs, characterized in that the cross member is integral with the upper bearings of the suspension springs, while the bushings of the axles of the lower suspension arms, brackets fastening the cross member, rack and pinion steering gear, anti-roll bar, upper suspension arms are mounted on the cross member, and the subframe mounting holes are made in the bracket on the mounting of the cross member so that the distance between the holes is in a ratio of at least 1: 3 to the distance between the mounting brackets of the cross member.

Description

The utility model relates to the field of engineering, in particular, to subframes of independent suspension of the front wheels of vehicles.

Known subframe independent suspension of the front wheels of the car, mounted on the frame of the car, containing the cross member and braces. The cross-member contains the cross-member mounting brackets fixed at its ends, the axle lower suspension arm bushings mounted motionless in the cross-arm mounting brackets, the upper suspension spring supports mounted on the cross-arm mounting brackets through amplifiers and each containing: a support bracket, a shock absorber cup, a guide gasket and a cup springs. Using stretch marks, an additional connection of the cross member with the frame of the vehicle [1].

The disadvantages of this design are:

- insufficient rigidity;

- increased complexity of manufacturing and metal consumption of the bracket securing the cross member;

- A large range of parts for installing elastic suspension elements.

The technical result achieved by the claimed solution is to increase the rigidity of the structure, reducing the range of parts and the complexity of their manufacture.

This result is achieved by the fact that the cross member is integral with the upper bearings of the suspension springs, while the bushings of the axles of the lower suspension arms, the brackets of the cross member, the rack and pinion steering gear, the anti-roll bar, the upper suspension arms are fixed to the cross member.

The inventive design solution is illustrated by drawings, where:

Figure 1 - Subframe of independent suspension of the front wheels of the vehicle (General view) (isometry);

Figure 2 - Subframe independent suspension of the front wheels of the vehicle (prototype).

The subframe of the independent suspension of the front wheels of the vehicle consists of a cross member 1 made integrally with the upper bearings of the suspension springs. Brackets for securing the cross member 2 are welded to the cross member on the left and right sides, which secure the subframe to the vehicle frame through holes "A", made so that the distance "B" between holes "A" is at least 1: 3 to the distance " B "between brackets 2.

In the lower part of the cross member, bushings of the axles of the lower levers 3 are welded.

Two brackets of the upper arms 4 are welded to the brackets of the cross member on the left and right.

Cups of shock absorbers 5 are welded into the supports, providing fastening of the shock absorber and a fixed position of the spring and its gasket in the radial direction.

On the crossbeam, the rack and pinion steering gear mounting brackets are right 6 and left 7, and the anti-roll bars 8 are attached.

The design of the subframe of the independent suspension of the front wheels allows you to create a single module on which the suspension elements are installed, as well as the rack and pinion steering gear and anti-roll bar, which significantly reduces the complexity of manufacturing a vehicle in mass production and increases the technical characteristics of the vehicle.
