Description

The torque rod structure of suspension system to car}

The present invention relates to a suspension device of a vehicle, and in particular, by improving a torque rod that minimizes the transmission of an impact force generated from a tire to a propeller shaft, breakage of the torque rod occurs during vehicle operation. Even if it is related to the torque rod of the vehicle suspension that can be easily repaired in the field.

Generally, the motor vehicle 1 has four wheel drive or rear wheel drive and front wheel drive.

In the four-wheel drive and the rear-wheel drive car (1) of the above-described vehicle, the engine power is transmitted by the propulsion shaft (propeller shaft) is made to run.

As described above, when the vehicle is driven and driven by the propulsion shaft, a lot of shocks are generated on the wheels (tires), and the impacts have a fatal effect on the propulsion shafts that transmit power. Is the torque rod 30.

The torque rod 30 is installed so as to minimize the transmission of the impact force generated from the wheel (tire) to the propulsion shaft, both ends are fixed to the axle (axle shaft) 2 and the body body 3, respectively. It is installed (see Fig. 1 or 2).

The conventional torque rod 30 installed and used as described above will be described in detail with reference to FIG. 3 as follows.

The conventional torque rod 30 includes a rod 10 having a predetermined length and having a ring-shaped assembly 11 at both ends;

One end of the pin 26 is an impact absorbing rubber 21 in which the pipe 22, which is forcibly fitted to the assembly portion 11 of the rod 10, is wrapped outside by vulcanization (heat welding). And a nut 25 screwed on the opposite side to which the shock absorbing rubber 21 is formed so as to be held in a state of being fitted to the axle (axle shaft) 2 or the body body 3. The bolt 23 is comprised by the end assembly 20 by which the process is formed.

As described above, the torque rod 30 is assembled by forcibly fitting the pipe 22 of the end assembly 20 to the assembly portion 11 of the rod 10.

In the above and the rod 10 and the end assembly 20 is assembled to the torque rod 30 is installed on the fixed bracket (4) installed on the axle (2) and the body body (3) of the vehicle (1), When the torque rod 30 is installed, the pins 26 of the end assembly 20 are respectively inserted and then the nut 25 is screwed into the bolts 23 formed on the pins 26 to complete the installation.

The torque rod 30 installed in the vehicle 1 as described above minimizes the impact force transmitted to the propulsion shaft by absorbing the shock generated in the wheels while driving the shock absorbing rubber 21.

However, the conventional torque rod installed and used as described above is, firstly, the pipe 22 of the end assembly 20 is assembled only in a state in which the pipe 22 of the end assembly 20 is fitted to the assembly portion 11 of the rod 10, and thus torque during driving of the vehicle. When the impact (vibration) is severely applied to the rod, there is a problem that the rod and the end assembly are separated; Second, since the rod 10 and the end assembly 20 are simply assembled by fitting, when the impact (vibration) is applied, the pipe has a disadvantage in that slip occurs in the assembly, thereby promoting wear on the assembly. In addition to being shortened, there is a problem that the use of reproduction is practically impossible; Third, there is a difficulty in improving the reliability of the product because it always contains the risk of injury to human life due to breakage of the torque rod (30).

In order to solve the above problems a little, automobile users may arbitrarily weld the rod 10 and the end assembly 20, which may damage the shock absorbing rubber 21 by welding heat during welding, Welding is only made on the outside, so the effect of improving stability is not obtained.

The present invention devised to solve the problems of the torque rod of the conventional vehicle suspension device, the one end of the pin of the end assembly assembled to the assembly of the rod constituting the torque rod, that is, the end of the end including the shock absorbing rubber A screw hole is formed on the side, and the anti-separation plate is fixed by bolts screwed into the screw hole. Even if the pipe of the end assembly is loosened in the assembly of the rod due to repeated impact force, the anti-separation plate is completely It is possible to prevent the departure, so that it is possible to prevent safety accidents and casualties due to torque rod breakage, as well as to improve the reliability of the product; Second, even if the torque rod breakage occurs during the operation of the differential vehicle, maintenance on the site is easy, and maintenance cost according to the maintenance can be reduced; Third, the present invention provides a torque rod structure of a vehicle suspension device capable of regenerating and using torque rods.

In addition, in order to prevent the separation of the rod and the end assembly is to provide a torque rod that does not need to do unnecessary work, such as welding work that the car users do arbitrarily.

The object of the present invention is to be connected to the axle (axle shaft) and the body body of a four-wheel drive or rear wheel drive vehicle to absorb the impact generated on the wheel (tire) to minimize the impact force on the propeller shaft A torque rod to be provided, comprising: a rod having a predetermined length and having ring-shaped assembly portions formed at both ends of the end assembly; A shock absorbing rubber, in which a pipe inserted into the assembly portion of the rod is wrapped outside by vulcanization (heat welding), is formed at one end of the pin 26, and the shock absorbing rubber is formed. A screw hole is formed on the side of the side to fix the release preventing plate with a bolt 50, and the side opposite to the end having the shock absorbing rubber is fixed to the axle (axle shaft) or the body body in a fixed state. An end assembly in which a bolt for processing the nut to be screwed is formed; The bolt is sized to be supported by the side of the assembly of the rod to prevent the end assembly assembled to the assembly of the rod, and bolted to the center by a screw hole formed in the pin of the end assembly Is achieved by a separation prevention plate having a bolt insertion hole formed therein.
