Abstract
The invention relates to a control and measurement tool of the toe-in of a front axle used for a steering oil cylinder and provided with double transverse pull rods, comprising a measuring rod assembly and a measuring support assembly. The control and measurement tool is characterized in that the measuring rod assembly comprises an installation screw rod (1), a positioning sleeve (3) is sleeved on the installation screw rod (1), a joint ball bearing (2) is arranged outside the positioning sleeve (3), a flexible connection connector (5) is arranged on the joint ball bearing (2), the flexible connection connector (5) is connected with a measuring rod (6), and the measuring rod (6) is provided with a graduated scale (7); the measuring support assembly comprises a support (9), the support (9) is provided with a through groove, and the support (9) is provided with a chamfered edge positioning pin (11) and a circular positioning pin (10) on a steering knuckle brake caliper mounting bolt hole positioned at the other side of the front axle. The control and measurement tool disclosed by the invention has the advantage of reasonable structural design on appropriately selecting a positioning datum and a measuring datum, solves the problem that a main pin shaft line is not perpendicular to a measurement plane by adopting the joint ball bearing (2) and can swing front and back and enables the measurement and regulation data to be more accurate by simulating the diameter and the position of a front wheel tire by using a measuring support.
Description
Technical field
The present invention relates to toe-in control and the measurement mechanism of propons before dispatching from the factory, especially a kind ofly be used to turn to the prenex control of the mid-pair of drag link propons of oil cylinder measurer.
Background technology
At present, the toe-in control that turns to mid-pair of drag link propons of oil cylinder all is behind the assembling entire vehicle, to adopt the method for measuring the four-wheel location to adjust control, and such propons is in that the entrucking toe-in is not uncontrollable.But carrying out the four-wheel location, oversize vehicle not only wastes fund, and very inconvenience of operation.
Summary of the invention
The object of the invention is exactly to turn to mid-pair of drag link propons of oil cylinder in the prenex uncontrollable problem of entrucking not in order to solve, and the present invention provides a kind of prenex control of mid-pair of drag link propons of oil cylinder measurer that is used to turn to.
The technical solution adopted for the present invention to solve the technical problems is:
Be used to turn to the prenex control of mid-pair of drag link propons of oil cylinder measurer; Comprise sounding rod assembly and measurement bracket assembly, it is characterized in that: described sounding rod assembly comprises the installation screw rod that is connected with propons one side stub, locating sleeve of suit on the screw rod; Locating sleeve is provided with a joint ball bearing outward; The joint of a flexible connection is installed on the joint ball bearing, and joint is connected with a sounding rod, and sounding rod is provided with rule; Described measurement bracket assembly comprises support, has a groove on the support, and support is provided with the chamfered edge register pin and is installed on the propons opposite side steering knuckle caliper erection bolt hole with the circle register pin.
On the basis of above-mentioned main technical schemes, can increase following further perfect technical scheme:
Described locating sleeve is a multidiameter, and multidiameter is provided with the central through hole of ladder, and wherein an end is the location end face.
Described support is a T shape support, evenly is provided with one group of through hole on the support.
Beneficial effect of the present invention can realize turning to measurement and the control to toe-in when entrucking not of mid-pair of drag link propons of oil cylinder: the propons after this gage measuring adjustment is qualified need not to carry out four-wheel positioning measurement again after the entrucking of car load factory, the car load toe-in no longer needs adjustment.
Reasonable in design: it is suitable that positioning reference and measuring basis are selected.Adopt the joint ball bearing to solve main pin axis and measure face out of plumb problem and can swing.Diameter and position with measurement bracket simulation front tyre make measurement adjustment data more accurate.
Easy to operate: this measurer is simple in structure, and sounding rod selects for use chapped pipe to make from heavy and light, can realize the one man operation.
Beam control system measurer can be suitable for left and right sides steering knuckle simultaneously before this.
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
