[0002] The function of the ABS hydraulic unit is to improve the braking performance of the vehicle, enhance driving safety, prevent the wheels from locking (that is, stopping rolling) during braking, thereby ensuring that the driver can still control the direction during braking and prevent the rear axle from skidding. The ABS hydraulic unit is used as a set in conjunction with wheel speed sensors, electronic control units ECU, ABS fault lights and other equipment.

[0003] The existing ABS hydraulic unit is installed in a deeper position in the vehicle body. When installing the ABS hydraulic unit, it is necessary not only to hold the ABS hydraulic unit for positioning, but also to operate the installation bolts to keep them in a vertical state, and at the same time, a screwdriver is used to tighten the bolts to fix the ABS hydraulic unit. The operation is complicated, and it is difficult for the staff to control more than one operation at the same time with both hands. The process is prone to mistakes, which wastes installation time and is very inconvenient. Utility Model Content

[0009] Furthermore, the larger end of the fixing bolt is installed on the inner side of the mounting hole and fits the end of the return spring away from the base plate, and the smaller end of the fixing bolt is installed on the inner side of the sleeve and the mounting hole, and a first knife groove is provided at the center of the end of the fixing bolt away from the base plate.

[0010] Furthermore, the auxiliary component is composed of a second corner block, which is installed at the four corners of the outer side of the hydraulic unit away from one end of the base plate. An internal thread groove is provided through the center of the second corner block away from one end of the base plate, and a cutout is provided at the angle of the second corner block away from the hydraulic pump.

[0011] Furthermore, an external thread groove is provided on the outer side of the larger end of the mounting bolt, and the mounting bolt is threadedly connected to the internal thread groove through the external thread groove. A cutter head installed in the first cutter groove is provided at one end of the mounting bolt close to the base plate.

[0012] Furthermore, a second rectangular groove is formed at one end of the mounting bolt away from the bottom plate, and a third cross-shaped groove is formed on an inner wall of the second groove close to the bottom plate.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0014] The utility model uses a first angle block and a sleeve, cooperates with a second angle block and a mounting bolt. Under the setting of the positioning hole and the sleeve on the inner side of the first angle block, the fixing bolt can be vertically installed on the inner side of the first angle block, keeping the vertical state during installation, facilitating the tightening operation, and eliminating the need for manual straightening assistance, thereby reducing the number of operating steps and difficulty in the process of installing the hydraulic unit. The staff only needs to control the positioning of the hydraulic unit inside the vehicle and tighten it with a screwdriver. The mounting bolt connected to the fixing bolt in the second angle block extends the control line of the fixing bolt. The staff can control the fixing bolt to tighten it through the mounting bolt under the operation of the screwdriver, effectively solving the problem that the hydraulic unit is installed too deep inside the vehicle, causing inconvenience for the staff to operate.
