Vehicle rear traction connection device

Abstract

The invention relates to a traction device, and provides a vehicle rear traction connection device in order to solve the technical problem of existing connection devices during use. The vehicle rear traction connection device comprises a connection ball, and the connection ball is fixed to the front end of a balance arm; the device is characterized by further comprising left and right wall plates,a rotating rod and a fixed rod; a clamping groove is formed between the left and right wall plates, the rotating rod is located in the clamping groove, one end of the fixed rod stretches into the clamping groove and is fixedly connected with the left and right wall plates, and a first hinge shaft penetrates through the tail end of the rotating rod; the tail end of the balance arm is located in the clamping groove, a pin shaft penetrates through the portion, in the clamping groove, of an arm body of the balance arm, and the balance arm can rotate freely around the pin shaft; a second hinge shaft penetrates through the tail end of the balance arm and a rod body of the front end of the rotating rod, arc sliding grooves are formed in the left and right wall plates respectively, and the two ends of the second hinge shaft are located in the arc sliding grooves of the left and right wall plates respectively. The connection device is reasonable in structure, has an obvious shock absorption effect, and can be widely applied to connection in traction operation.

Description

technical field [0001] The invention relates to a traction device, in particular to a device for being fixed at the rear of a vehicle and connected with a traction type caravan. Background technique [0002] The trailer connection device with a ball joint is the most common, especially when ordinary vehicles are used to tow the RV, the ball joint connection device is widely used because of its small size, easy installation, and free swing. In order to ensure the normal use of the ball head connector, it is required that the ball head always maintain a vertical upward posture after connection. However, the models and specifications of the towing vehicle and the towed vehicle are different, and the height difference between them is not fixed. , when the height difference between the towing vehicle and the towed vehicle changes, it is difficult to meet the needs of the fixed structure of the ball joint connection device, so it is necessary to provide a connection device that ca...

Problems solved by technology

In order to ensure the normal use of the ball head connector, it is required that the ball head always maintain a vertical upward posture after connection. However, the models and specifications of the towing vehicle and the towed vehicle are different, and the height difference between them is not fixed. , when the height difference between the towing vehicle and the towed vehicle changes, it is difficult to meet the needs of the fixed-structure ball joint connection device, so it is necessary to provide a connection device that can adapt to the different height differences between the towing vehicle and the towed vehicle
