Description

 The invention relates to a transport mechanical engineering and can be used to install a headlight cleaner gear motor on a vehicle body, for example, a car.

 It is known (see 1) a fastening device for a gear motor of a headlight cleaner for a VAZ-2108 automobile. The cleaner is installed on the panel of the radiator frame of the car body using the bracket. The bracket is equipped with two closely spaced weld bolts, with which it is attached to the body. A slot is made in the bracket to connect to the cleaner’s gear motor housing. The motor gear reducer is connected to the bracket by inserting the threaded sleeve of the motor gear reducer housing into the slot and screwing the nut onto the sleeve. The presence of a slot allows the installation of a cleaner in case of deviations in body size.

 The device has the following disadvantages.

 Low accuracy of mounting the bracket relative to the body, due to the small distance between the mounting bolts.

 The high complexity of the installation of the cleaner, due to the mounting of the bracket with two bolts.

 The need to adjust the position of the gear motor cleaner relative to the bracket due to the lack of precise positioning of the gear motor on the bracket.

 For the prototype of the claimed device, the fastening device of the motor reducer of the headlight cleaner of the VAZ-2110 is taken. It includes a bracket (see 2, part 2110-3756040) and the lower cross member of the radiator frame of the front of the body (see 3, part 2110-8401078).

 The bracket is equipped with a hole for attaching the motor reducer of the cleaner and a welded bolt for connecting to the lower cross member of the body radiator frame.

 The lower cross member of the radiator frame of the front of the body is equipped with an opening for mounting the bracket and an opening for the motor-reducer shaft of the headlight cleaner.

 The use of one threaded connection for mounting the bracket on the body reduces the complexity of installing a cleaner gear motor on the car body.

 The disadvantage of the mounting device is the lack of means for setting the position relative to the body on the bracket, which leads to significant errors in orienting the position of the cleaner’s motor reducer shaft relative to the body and, consequently, to an increase in the time required for the correct installation of the cleaner.

 The invention solves the problem of reducing the complexity of installing a gear motor cleaner on a vehicle body and improving the accuracy of orienting the shaft of the gear motor cleaner relative to the vehicle body.

 These tasks are solved in the device for attaching the motor reducer of the headlamp cleaner, which includes a bracket provided with a threaded element and a hole for attaching the motor reducer of the headlamp cleaner, and a body part of the vehicle equipped with an opening for the shaft of the cleaner and a mounting hole. The problems are solved in that the bracket is provided with a tongue formed at the end of the bracket remote from the threaded element, and the tongue is located in the hole for the cleaner motor reducer shaft. An emphasis can be made on the bracket to limit the movement of the tongue (and the bracket as a whole) in the hole for the gearmotor shaft. In this case, the emphasis may abut the tongue.

 The task of increasing the accuracy of orientation of the shaft of the motor reducer of the cleaner is achieved through the use of a tongue fastener inserted into the opening of the body part in the design of the device, and due to the spatial diversity of the location of the threaded element and tongue. The presence of a stop also increases the accuracy of orientation by restricting the movement of the tongue in the hole of the body part.

 The task of reducing the laboriousness of assembling a vehicle is solved by using one threaded fastener for mounting the bracket on the body and by simplifying visual control during assembly due to the use of an opening in the body part for the gear motor shaft to limit the movement of the tongue (and the bracket as a whole).

 The invention is illustrated by the following drawings.

 In FIG. 1 shows the cleaner bracket, main view.

 In FIG. 2 shows a wiper bracket, sectional side view.

 In FIG. Figure 3 shows the installation of the motor reducer of the headlight cleaner on the VAZ-2110 car body.

 In the bracket 1 of the motor reducer of the headlight cleaner (see Fig. 1,2), one or more holes 2 are made for attaching the housing of the motor reducer of the cleaner. A threaded element 3 is fixed at one end of the bracket. A tongue 4 is formed at the opposite end of the bracket 1. An emphasis 5 is attached to the tongue 4. The bracket 1 (see Fig. 3) with the headlight cleaner cleaner gearbox 6 mounted on it is mounted on the body part 7. In part 7, a hole 8 is made for mounting the bracket 1 and a hole 9 for the shaft 10 of the gear reducer 6. The hole 9 has an oblong shape. The tongue 4 and the shaft 10 are passed into the hole 9. The bracket 1 is fixed to the part 7 using the threaded element 3 of the bracket 1.

 The bracket 1 can be made by stamping from sheet steel. As a threaded element 3, a weld bolt can be used.

 The motor reducer 6 (see Figure 3) is fixed on the bracket 1 with screws 11. The bracket 1 with the motor reducer 6 is mounted on the body part 7, which is used on the VAZ-2110 car the lower cross-member of the radiator frame. When installing, close the tab 4 of the bracket and the shaft 10 of the gear motor 6 are inserted into the hole 9 of the cross member 7, and the welded bolt 3 is inserted into the hole 8, after which the nut 12 is screwed onto the bolt 3. The stop 5 restricts the movement of the tab 4 (and the bracket 1 as a whole) in the direction of the hole 9, and the tab 4 limits the movement of the shaft 10 of the gear motor 6 in the hole 9.
