Description

Automatic centering and self-locking device for tire ride comfort test bench
Technical Field
The invention relates to the technical field of tire ride comfort test beds, in particular to a self-locking device capable of automatically centering.
Background
The six-component characteristic of the tire moving on the uneven road surface can be used for building a tire smoothness model and applied to the whole vehicle simulation, and the smoothness matching research of the tire and the whole vehicle is carried out, so that the design of the tire is guided. The tire smoothness test bench is important equipment for testing six-component characteristics of tires moving on uneven road surfaces.
Under the impact of uneven road surfaces, the condition that the position of the wheel center of the tested tire is kept unchanged is an important condition of the tire smoothness testing test bed. The existing tire smoothness test bed approximately keeps the wheel center position unchanged by controlling the load of a loading cylinder, so that the impact force test is not accurate enough. And the operation is complex and time-consuming due to the control of some devices by a mechanical bolt, and the devices need to be matched by multiple persons.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides an automatic centering and self-locking device for a tire ride comfort test stand. The load centering loading that can realize making things convenient for fast, and keep the uneven road surface impact in-process test tire wheel center position unchangeable, realize the accurate test of impact force.
An automatic centering and self-locking device for a tire ride comfort test bed comprises a test bed base, a test bed vertical plate, a load loading cylinder, a linear guide rail, a tire mounting flat plate with an inclined surface and a sliding block, a locking hydraulic cylinder, a balance two-force rod, a wedge block with a sliding groove and a locking shell. The test bed comprises a test bed base, a test bed vertical plate, a load loading cylinder, a locking shell and a sliding block, wherein the test bed base and the test bed vertical plate form a test bed main body, the load loading cylinder and the locking shell are fixed on the test bed main body, a tire installation flat plate with an inclined surface and a sliding block is connected with the test bed main body through a linear guide rail, two locking hydraulic cylinders are symmetrically arranged on two sides of the tire installation flat plate with the inclined surface and the sliding block and are connected with the tire installation flat plate through hinges, two balancing two force rods on each side are connected with the locking hydraulic.
Compared with the prior art, the invention has the beneficial effects that:
1. the balance two-force rod has novel and unique structure and can realize automatic centering in the locking process.
2. The structure is simple and reasonable, the rapid locking can be realized after the tire applies load, and the locking device is simple and reliable.

Detailed Description
As shown in fig. 1, an automatic centering and self-locking device for a tire smoothness test bed comprises a test bed base 1, a test bed vertical plate 2, a load loading cylinder 3, a linear guide rail 4, a tire mounting flat plate 5 with an inclined surface and a sliding block, a locking hydraulic cylinder 6, a balancing two-force rod 7, a wedge block 8 with a sliding groove and a locking shell 9; the test bed base 1 and the test bed vertical plate 2 form a test bed main body, the load loading cylinder 3 and the locking shell 9 are fixed on the test bed main body, the tire installation flat plate 5 with the inclined plane and the sliding block is connected with the test bed main body through a linear guide rail, the two locking hydraulic cylinders 6 are symmetrically arranged on two sides of the tire installation flat plate 5 with the inclined plane and the sliding block and are connected with the tire installation flat plate 5 through hinges, the two balancing two force rods 7 on each side are connected with the locking hydraulic cylinders 6 through one ends of the hinges, and the other ends of the balancing two force rods are connected with the two wedge-shaped blocks.
The working principle of the invention is as follows:
as shown in fig. 2, when the locking hydraulic cylinder 6 acts, the applied force F1 acts on the two sliding-groove-equipped wedge blocks 8 through the two locking two-force rods 7, and the forces F21 and F31 acting on the two sliding-groove-equipped wedge blocks 8 are equal in magnitude, and simultaneously the force component F2y of the force F21 in the y-axis direction and the force component F3y of the force F31 in the y-axis direction act on the centering axis with equal and opposite moments, so that automatic centering during locking is realized.
As shown in fig. 3, after the tire mounting plate 5 with the inclined plane and the sliding block moves to a target load position, the locking hydraulic cylinder 6 applies a thrust force, the force is transmitted to the two wedge blocks 8 with the sliding grooves through the two balancing two-force rods 7, the wedge blocks 8 with the sliding grooves move along the sliding block on the tire mounting plate 5 with the inclined plane and the sliding block in a guiding manner, and along with the downward movement of the wedge blocks 8 with the sliding grooves, the wedge blocks expand tightly in the locking shell 9 to generate a self-locking effect, and then the locking hydraulic cylinder 6 can be unloaded, and the self-locking state is still maintained. When the uneven road surface generates upward impact on the tire, the tire mounting flat plate 5 with the inclined surface and the sliding block tends to slide upwards relative to the two wedge blocks 8 with the sliding grooves, so that the locking force is increased, the tire mounting flat plate 5 with the inclined surface and the sliding block is prevented from moving upwards, and the wheel center position of the tire is kept unchanged all the time.
