Description

Press mounting mechanism for auxiliary frame positioning and auxiliary press mounting of vehicle body spring

Technical Field

The utility model relates to the field of vehicles, in particular to a press-fitting mechanism for positioning an auxiliary frame and assisting press-fitting of a vehicle body spring.

Background

The multi-channel road simulation test is an important indoor test verification link in the automobile development process. Before a multichannel road simulation test is performed in a laboratory, a chassis system including an auxiliary frame, a control arm, a connecting rod, a shock absorber, a coil spring, a steering gear, a brake system, and the like needs to be temporarily assembled. When the rear suspension of the automobile adopts an independent suspension, a multi-link type independent suspension is generally adopted, and a coil spring of the suspension is separated from a shock absorber.

With the pursuit of improvement of the comfort of the automobile, large automobiles such as SUVs are more and more popular, and the coil springs in the automobile suspension are changed into springs with higher rigidity, so that the difficulty of installing the springs in a laboratory is increased.

Generally, after the subframe is mounted, it is necessary to start mounting the coil spring, compress the spring by a spring compression tool, and then feed the compressed spring to the spring mounting position. The tools for compressing springs are mainly of two types, one is a claw type compression tool, and the other is a sliding column screw rod type spring compression tool.

Fig. 1 is a schematic view of a jaw type compression tool in the prior art. As shown in fig. 1, a pair of holding claws 12 is arranged on a screw rod 11 of a claw type compression tool 10, which can hold a spring, and two sides of the spring are respectively provided with a claw type compression tool, which can firstly compress the spring and then send the spring into a loading position, and the method has the defects that:

firstly, because the claw hook of the holding claw 11 is not completely matched with the spring, the claw hook can damage the rubber protective layer on the surface of the spring, thereby causing complaints of test entrusters, and the spring needs to be replaced under severe conditions.

Second, after the spring is loaded into the mounting position, the compression tool may not be smoothly removed and need to be removed again, resulting in increased workload.

When the spring is placed in the mounting position, even if the end faces of the upper spring pad and the lower spring pad are attached to the end faces of the spring, the spring rotates to a certain degree after the spring is loosened, the end face of the spring is separated from the end face of the spring pad, so that the separation gap is too large, and rework is needed when the problem that the loading requirement cannot be met is caused.

Fourthly, when the spring stiffness is very high, the phenomenon of difficult compression can appear in ordinary claw hook type spring compression tool, and the problem of dangerous working conditions such as screw rod bending, claw hook escaping from the spring can also appear.

Fig. 2 is a schematic structural view of a prior art strut screw spring compression tool. As shown in fig. 2, the screw 21 of the strut screw spring compression tool 20 is provided with a pair of clasps 22, which also has the second and third disadvantages of the former tool. Both of these tools are not suitable for coil spring and shock absorber split suspension system test stand construction.
