Description

Engine Rear Suspension Device for Ultraminiature Four-wheel Vehicle

1. Technical field:

The utility model relates to a vehicle accessory, in particular to an engine rear suspension device for an ultra-miniature four-wheel vehicle used for connecting the engine with the vehicle frame.

2. Background technology:

At present, in order to meet the needs of the rural areas and foreign markets, the ultra-miniature four-wheel vehicle has been successfully developed, and the engine of this ultra-miniature four-wheel vehicle generally adopts a common motorcycle engine. In a two-wheeled or three-wheeled motorcycle, the engine is usually directly connected to the frame through the hanging lug (or bracket). Since they are rigidly connected, the engine will generate vibration when it is working, and the vibration will pass directly through the engine hanging lug ( or bracket) and the suspension of the frame are transmitted to the frame, causing the vehicle to vibrate greatly, affecting the stability of the vehicle, making the ride uncomfortable, and may cause safety accidents; , Size is bigger, the higher shock absorber of price is connected with vehicle frame, and this type of shock absorber is not suitable for the motorcycle engine that size is small, light in weight, also can't satisfy the low-cost requirement of ultraminiature four-wheel vehicle.

3. Contents of the invention:

The purpose of the utility model is to provide a superminiature four-wheel vehicle engine rear suspension device with simple structure, less space occupation, low cost and good damping effect.

The technical scheme of the utility model is: it includes a rear bracket, and its structural features are: the rear bracket beam is fixedly connected to the rear bracket beam, the rear bracket beam is provided with mounting holes, and the upper and lower ports of the mounting holes are respectively fixed with shock-absorbing glue Pad seat ring.

In the utility model, a rear bracket crossbeam is fixedly connected to the rear bracket, and shock-absorbing rubber seat rings are respectively fixedly connected to the top and bottom of the mounting holes of the rear bracket cross-beam. The bushing is connected to the frame with connecting bolts. The connecting bolts should be covered with bushings. The rear bracket is connected to the engine casing through the mounting holes on it. The vibration generated when the engine is working can be minimized by the shock absorbing rubber sleeve. Absorption, thereby reducing the vibration transmitted from the engine to the frame.

The utility model has the advantages of being able to absorb the vibration transmitted from the engine to the vehicle frame, thereby reducing the vibration of the vehicle, enhancing the stability of the vehicle, making driving more comfortable and safe, and having a simple structure, less space, and low cost. Low.

4. Description of drawings:

Fig. 1 is a structural representation of the utility model;

Fig. 2 is a left side view of Fig. 1 .

5. Specific implementation methods:

As shown in Figure 1: the utility model is composed of a rear bracket 1, a rear bracket beam 2, a shock-absorbing rubber pad seat ring 4, an exhaust pipe hanger 5 and a bushing 7, and its structural characteristics are: fixed on the rear bracket 1 Connected to the rear support beam 2, the rear support beam 2 is provided with a mounting hole 3, and the upper and lower ports of the mounting hole 3 are fixedly connected with a shock-absorbing rubber pad seat ring 4 respectively.

It can be seen from Fig. 1 and Fig. 2 that an exhaust pipe hanger 5 is arranged at one end of the rear bracket beam 2, so that it can support the engine exhaust pipe at the same time; There are mounting holes 6 for the reverse gear shaft on the plate, and a bush 7 is arranged in one of the reverse gear shaft mounting holes 6, through which the reverse gear shaft of the engine can pass to be supported on the rear bracket 1; On the board, the shock-absorbing rubber pad seat ring 4 is welded on the rear support beam 2.

When installing, install shock absorbing rubber sleeves in the upper and lower shock absorbing rubber pad seat rings 4, and connect them to the frame beam with connecting bolts. The connecting bolts should be covered with bushings, and the front bracket is connected to the engine through the mounting holes 8 on it. The shells are connected, and the vibration generated when the engine is working can be absorbed by the shock-absorbing rubber sleeve to the maximum extent, thereby reducing the vibration transmitted from the engine to the frame.
