Quasi-rhombic coach

Abstract

The invention discloses a rhombus coach, comprising a chassis and a coach body positioned on the chassis, wherein, the chassis comprises a frame, and a front wheel, a rear wheel, a left middle wheel and a right middle wheel which are arranged on the frame in rhombus shape, wherein, the front wheel and the rear wheel are connected with a steering mechanism, the left middle wheel and the right middle wheel are connected with a driving mechanism; the front end of the coach body takes the shape of a shuttle, a steering wheel of the steering mechanism is arranged at the middle part of the front endof the coach body. The invention is a rhombus coach which has small wind resistance, low energy consumption, small turning radius, flexible operation, good trafficability characteristic, good ride and light weight.

Description

technical field [0001] The invention mainly relates to the field of vehicle engineering, in particular to a diamond-shaped passenger car. Background technique [0002] With the emergence of the fuel crisis, energy saving has become a top priority in the design of various vehicles for current vehicles. For vehicles with large volume, heavy passenger capacity and high energy consumption like passenger cars, how to reasonably design the body structure and reduce the drag coefficient so that it can reduce fuel consumption when driving at high speed has become an effective means of energy saving. When designing the front end of a traditional four-wheeled rectangular vehicle, due to the layout of the front wheels and the driver's layout requirements, the front end of the body cannot be made into a shuttle-like shape, and the drag coefficient cannot be optimally reduced. Secondly, traditional passenger cars have large dimensions, long wheelbase, and large turning radius. When driv...

AI Technical Summary

Problems solved by technology

When designing the front end of the traditional four-wheeled rectangular vehicle, due to the layout of the front wheels and the layout requirements of the driver, the front end of the body cannot be made into a shuttle-like shape, and the drag coefficient cannot be optimally reduced.

Secondly, traditional passenger cars have large dimensions, long wheelbase, and large turning radius. When driving to places with narrow steering space, such as tourist attractions and busy city streets, it is easy to make it difficult to turn around.

Shortening the wheelbase may lead to poor anti-pitch ability and poor ride comfort

Third, the layout of the body is low, resulting in smaller approach angles, departure angles, and longitudinal passing angles, and poor passability. If the layout of the body is high, the center of mass of the vehicle will be raised, resulting in poor handling stability. This is especially true for heavy passenger cars
