Description

Automotive Retarder Mounting Device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retarder mounting apparatus for automobiles, and more particularly, to a retarder mounting apparatus for automobiles that prevents linear movement and rotational movement by fixing the retarder at four positions in the longitudinal and transverse directions, respectively. will be.

In general, the retarder serves as an auxiliary brake of a large vehicle, and is mounted between the propeller shafts to hold the propeller shaft drive through the electric current therein. It is preferable for the driver to operate the retarder by operating the operating lever in the driver's seat rather than operating the foot brake in a driving environment such as a downhill road, in consideration of the foot brake fade or wear.

In order to mount such a retarder on the propeller shaft, the retarder must be fixed to a frame or the like. In the related art, bolts are laterally fastened to both sides of the frame where the propeller shaft and the like are located.

However, since the weight of the retarder is 300 kg and the running state is not always smooth, unstable movements such as rotating in the front and rear directions, left and right directions, or linear movements appear.

As described above, it can be seen that a technique for mounting a conventional retarder for a vehicle is becoming more common.

The present invention has been invented to solve the above problems, an object of the present invention is to fix the retarder to the frame in the longitudinal direction and the transverse direction, respectively in four positions to prevent the linear movement and rotation movement of the vehicle retarder mounting apparatus In providing it.

In order to achieve the above object, the present invention is coupled to the center of the left and right sides of the retarder, the lateral extension portion formed toward the length and the frame and the fixing portion formed toward the lateral extension portion and mounted to the frame in the front-rear direction and the The retarder mounting device for a vehicle, characterized in that composed of a silent block portion that is located between the lateral extension and the fixed portion to connect.

According to a preferred embodiment of the present invention described above, if a silent block part is placed in the middle of the lateral extension parts mounted on both sides of the retarder, and the fastening part is fastened with a bolt or the like in the front-rear direction, as well as the front-rear direction and the left-right direction Firmly fixed to prevent linear movement and rotational movement.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention.

The technical idea of the present invention is that the retarder is in the vertical direction as well as the front and rear directions and the left and right directions on the frame.

FIG. 1 is a plan view showing a state in which the retarder mounting apparatus 1 for a vehicle according to an embodiment of the present invention is applied. In the present invention, the retarder 100 is horizontally fastened to both sides of the center in the width direction of the retarder. Lateral extension 10 for preventing directional rotation, and fixing portions 12, 12a and 12 'mounted in the front and rear directions of the lateral extension 10 and 10', respectively, to prevent back and forth swings. (12a '). Also, in the figure, a circle between the mounting bracket 10 and the fixing part 12, 12a, 12 ', 12a' is shown, which is more firmly coupled to the fixing part in the lateral extension 10. The silent block portions 14, 14a, 14 'and 14a' are shown.

FIG. 2 is a view showing a state in which the retarder mounting apparatus 1 for automobiles according to the embodiment of the present invention is applied.

In the drawing, the fixing parts 12, 12a, 12 'and 12a' are fastened to the inside of the frame 102 by bolts, and lateral extensions 10 and 10 'are provided on both sides of the retarder 100. It is installed, it can be seen that the bolt is fastened through the silent block portion 14, 14a (14 ') 14a' below the lateral extension (10) (10 ').

3 is an exploded perspective view showing the structure of the retarder mounting apparatus 1 for automobiles of the present embodiment.

The lateral extension 10 mounted in the lateral direction of the retarder 100 forms a lateral fixing piece 20 in a lateral direction toward the frame, and forms a vertical fixing piece 22 in a vertical direction. The lateral fixation piece 20 is supported by support pieces 24 and 24 'before and after the vertical fixation piece 22.

Bolt holes B are formed at the front and rear sides of the lateral fixing pieces 20, and the fixing portions 12, 12a, 12 'and 12a' are fastened thereto. In addition, bolt holes B1 are formed in the upper and lower sides of the vertical direction fixing piece 22, respectively, in order to be fixed to the side of the retarder 100. By the way, the bolt hole (B1) is formed in the retarder 100 toward the retarder 100 is formed with a step 26 having a diameter larger than the diameter of the hole in the direction in which the spring washer (W) is accommodated at the time of mounting Generate elastic force.

By the way, four spring washers W are mounted in one bolt hole B1. Two spring washers W are received at the ends 26 of the bolt holes B1 to generate elastic force. The two washers facing the side of the retarder 100 form a constant gap between the retarder 100 and the lateral extension 10 to prevent damage to the retarder 100.

The fixing part 12 forms a fixing plate 30 so as to stand upright in a vertical direction toward the frame, and is fastened to the frame using bolts formed in the upper, lower, left, and right bolt holes.

In addition, the fastener 32 is formed toward the lateral extension 10, and is connected to the bolt hole B of the lateral fixing piece 20 formed in the lateral extension 10.

The fastener 32 is a fixed cylinder 33 having a constant inner diameter in the vertical direction, an extension piece 34 and the extension piece 34 for extending the fixed cylinder 33 laterally from the fixed plate 30. It consists of a support piece 35 for supporting the fixed plate 30.

The cylindrical block portion 14 is fitted to the cylinder 33 of the fixture 32, which has a vertical shaft 40 formed with a bolt hole made of steel or the like in the center of the vertical direction, and absorbs external vibration to the outside thereof. The suction member 42 is made of rubber.

The suction member 42 of the silent block portion 14 forms a diameter corresponding to the diameter of the cylinder 33 in a direction fitted to the cylinder 33, and includes an upper side of the cylinder 33 in the fitted state. It is shaped to say.

In addition, the shim 36 is mounted to be in contact with the bolt head for the purpose of preventing damage in fastening the silent block part 14 with the bolt.

Therefore, in the retarder mounting apparatus for automobiles according to the present invention, fixing parts 12, 12a, 12 'and 12a' are fastened by bolts to the inside of the frame 102, and both sides of the retarder 100 are fastened. The lateral extension 10, 10 'is mounted.

The lateral extension portions 10 and 10 'are fastened with bolts through the silent block portions 14, 14a, 14' and 14a 'on the lower side thereof, so that the lateral extension portions are moved up and down, as well as before and after. Firmly fix the direction and left and right direction to prevent the linear movement and rotational movement.

As described above, the vehicle retarder mounting apparatus according to the present invention has an effect of maintaining the retarder in a stable state despite a severe driving state.

Since what has been described above is merely a mere example in all respects, the present invention should not be limitedly interpreted based on this. Therefore, modifications and equivalent implementations that fall within the vested technical spirit and scope of the present invention shall fall within the claims of the present invention.
