Amphibious vehicle suspension folding and unfolding mechanism

Abstract

The invention discloses an amphibious vehicle suspension folding and unfolding mechanism. An existing amphibious vehicle suspension folding and unfolding mechanism is large in occupied space, slow in folding and unfolding response and large in suspension structure improvement. According to the amphibious vehicle suspension folding and unfolding mechanism, the bottom of an A-shaped lower supporting arm is connected with a vehicle frame in a hinged mode, the top of the A-shaped lower supporting arm is hinged to the bottom of a steering knuckle, the middle portion of the steering knuckle is connected with a wheel in a hinged mode, and the top of the steering knuckle is fixedly connected with a cylinder body of a shock absorber. A spiral spring and a connecting disc are sleeved on a piston rod of the shock absorber, and the piston rod of the shock absorber is fixedly connected with a licking conical head. A spiral spring is connected between the cylinder body of the shock absorber and the connecting disc. The connecting disc is connected with a connecting rod in a hinged mode, the connecting rod is fixedly connected with a piston rod of a drive oil cylinder, and a cylinder body of the drive oil cylinder is connected with the vehicle frame in a hinged mode. A locking conical rod and a conical rod spring are arranged inside the locking conical head. The conical rod spring is connected between the locking conical rod and the locking conical head. The locking conical head and the locking conical rod are integrally arranged in a locking conical sleeve. The locking conical sleeve is fixedly connected with the vehicle frame. A notch is formed in the side wall of the locking conical sleeve. The amphibious vehicle suspension folding and unfolding mechanism is small in occupied space, high in folding and unfolding respond speed and capable of maintaining a suspension original structure.

Description

technical field [0001] The invention belongs to the field of vehicle engineering, and relates to a suspension folding mechanism, in particular to an amphibious vehicle suspension folding mechanism. Background technique [0002] The amphibious vehicle has the characteristics of both a vehicle and a boat, and can not only adapt to the changeable terrain of land and coastal beaches, but also adapt to the complex water environment. Therefore, it has broad application prospects in transportation and military affairs, and has gradually become a research hotspot in the field of automobiles. When the amphibious vehicle is running on land, the wheels need to support the vehicle body to realize the advancement of the vehicle, and when driving in the water, the wheels need to be retracted to the vehicle body to reduce its driving resistance in the water. The existing amphibious vehicle folding mechanism has defects such as large space occupation, slow response speed of wheel folding, ...
