The utility model belongs to the technical field of the car, concretely relates to car front suspension tie rod rack calibration device for the rack calibration work of car front suspension tie rod.
Background
The tie rod is an important part in the steering mechanism of the automobile, directly influences the stability of automobile operation and the driving safety, and plays an important role in transmitting motion in a steering system. Therefore, accurate study of the working load of the tie rod plays a decisive role in the design of the automobile steering system.
The current general test method for the working load of the tie rod is to paste a strain gauge on the tie rod, measure the load-strain coefficient of the tie rod by a rack calibration method, and measure the strain of the tie rod to obtain the working load of the tie rod.
But the problems existing now are: in the actual rack calibration process of the tie rod, due to the special structure of the tie rod, the tie rod is difficult to be calibrated by simply stretching or compressing the tie rod like a common two-force rod, and the calibration work of the tie rod is difficult to be completed quickly and accurately only by building a complete knuckle system and relying on an actuator to complete the complex calibration work.
Patent document 1 discloses a tie rod of an angle steel structure, which includes a tie rod assembly, wherein the tie rod assembly is composed of a ball head assembly, a bolt, a spring washer, a nut, a hoop and a tie rod, the round hole of the hoop is installed in the shaft diameters of two ends of the tie rod, the bolt passes through two round holes on the side surface of the hoop, the spring washer is sleeved in the thread diameter of the bolt, the nut is screwed in the bolt, and the thread diameter of the ball head assembly is screwed in the thread holes at two ends of the tie rod. The tie rod comprises two pipe joints and an angle steel, and two pipe joints welded fastening are at the angle steel both ends, and the shaft diameter that the pipe connects is laminated with the medial surface of angle steel, forms two sharp contacts. The round pipe joint is of a round pipe structure, and a threaded hole is formed in the end part of the round pipe joint and used for connecting the ball head assembly; two 180-degree symmetrical rectangular grooves are formed in the periphery of the circular pipe joint and used for locking the hoop. This tie rod changes the angle steel structure into through the section with the tie rod by traditional pipe structure, reduces tie rod's weight and cost, thereby can not solve through building complete knuckle system and rely on the actuator to accomplish complicated demarcation work's problem.
Patent document 2 discloses an inspection device, in particular a tie rod joint inspection device, which has a joint cushion block, wherein one end of the joint cushion block is provided with an upward protrusion, the bottom of the other end of the joint cushion block is provided with a bracket, one end of the joint cushion block, which is provided with the upward protrusion, is connected with a sliding block, and the sliding block is provided with a limiting device. Can detect straight shape and curved joint, convenient operation moreover detects fastly.
Patent document 3 relates to a tie rod assembly including a tie rod body, a tie rod ball pin and a joint, the tie rod ball pin and the joint being connected by a thread; two ends of the tie rod body are provided with internal threads, a first bolt is radially arranged at the front end of the tie rod body in the horizontal direction, an axial opening is arranged in the vertical direction, and a hoop is arranged at the outer side of the tie rod body beside the first bolt; one end of the joint is sequentially provided with a boss and a thread section matched with the internal threads at the two ends of the tie rod body, and the center of the thread section is provided with an axial groove; a locking nut is arranged at the joint of the thread section and the tie rod body; the spring is arranged between the locking nut and the boss and sleeved outside the thread section. However, the special tie rod assembly solves the problems of reducing the abrasion of threads and prolonging the service life of the steering tie rod, and cannot be used for conveniently calibrating a rack.
Disclosure of Invention
In order to solve prior art and mark the in-process at the actual rack of tie rod, because tie rod's special construction is difficult to carry out simple drawing or compression and mark like ordinary two power poles, thereby can only rely on the actuator to accomplish complicated demarcation work through setting up complete knuckle system, consequently hardly accomplish the problem of the demarcation work of tie rod fast, accurately, the utility model provides a suspension tie rod rack calibration device before the car for the work is markd to the high-efficient quick accurate rack of accomplishing tie rod.
The utility model aims at realizing through the following technical scheme:
a calibration device for a steering tie rod rack of an automobile front suspension comprises a bracket, a first fixing device and a second fixing device, wherein the bracket is used for sleeving and supporting the ball head part of a steering tie rod; the bracket outside is equipped with the pull ring.
Preferably, the tab is integrally formed with the bracket.
Furthermore, the pull ring is transversely arranged in the middle of the outer wall of the bracket.
Preferably, the inner shape of the bracket matches the shape of the ball head of the tie rod.
Furthermore, a clamping groove is formed in one side, opposite to the pull ring, of the support seat and used for containing the wall of the tie rod, and the ball head of the tie rod can be placed into the support seat.
The working principle of the utility model is briefly introduced as follows:
during calibration, the middle steering gear part of the tie rod is fixed on a test bed, a calibration device is sleeved into the ball head part of the tie rod from the bottom of the ball head end, and pull rings of the device are respectively connected with a load tension meter and an applied load in series.
