Description

Crawler-type swing arm suspension type travelling mechanism and crawler

Technical Field

The utility model relates to a tracked vehicle that track type swing arm suspension type running gear and designed based on track type swing arm suspension type running gear belongs to tracked vehicle running gear technical field.

Background

The vehicles are mainly divided into wheeled vehicles and tracked vehicles according to the walking mode. Both wheeled vehicles and tracked vehicles include a running gear and a suspended running gear is one of the running gears.

When the running mechanism of the wheeled vehicle and the tracked vehicle is designed, the swing arm can be involved, and the swing arm can play different roles in the vehicle according to actual needs.

In a wheeled vehicle, a swing arm may be used to form a suspension (or suspension) at the bottom of the front portion of the vehicle, typically serving as a connection and support between the vehicle's drive train and the wheels. See, for example, chinese utility model patent publication No. CN2787486Y, "swing arm type vehicle suspension". In addition, the swing arm can also be arranged on the side surface of the vehicle body and is represented as an active swing arm, which can be called as a rocker arm, and the purpose of the swing arm is to realize obstacle crossing for the vehicle. For example, refer to the chinese invention patent "obstacle surmounting articulated vehicle eight wheel drive system" with publication number CN 104590420A. As seen from the practical design, the running mechanism of the wheeled vehicle is relatively simple, so that the arrangement space of the swing arm is large, and the arrangement flexibility is strong.

However, the running mechanism of the crawler vehicle is relatively complicated compared to the wheeled vehicle, and thus the layout space for the swing arms becomes narrow, and the layout manner similar to the wheeled vehicle cannot be adopted.

In tracked vehicles, swing arms are widely used to form suspension systems with torsion shafts, in which case they may also be referred to as balance elbows. The suspension system has a solid and reliable structure, but is arranged at the bottom of a vehicle body, and the components are complex, so that time and labor are wasted in replacement and maintenance, the suspension system is generally used for medium-sized and heavy military vehicles with the scale of tens of tons to tens of tons, and the use of the suspension system on civil vehicles is very limited. In addition, the suspension system is bulky and has poor arrangement flexibility, and if functions such as tensioning are required to be added, a large number of parts are required to be additionally added, so that the whole system becomes more complex.

The swing arm can also be used for switching between three walking modes of wheels, tracks and legs in a tracked vehicle, for example, a chassis provided in the Chinese invention patent 'a swing arm type double-joint wheel-track composite special engineering vehicle chassis' with the publication number of CN102745259A, which comprises a vehicle frame, a main axle assembly, a half-bridge assembly and a leg assembly. In the patent of the invention, the swing arm well realizes the walking switching among the wheels, the track and the legs, but the swing arm has small movement (swing) range, cannot play the roles of automatic tensioning and suspension vibration reduction on the track, cannot accurately adjust the tensioning amount of the track, and has the defects of complex structure and poor practicability.

At present, a suspension system, a tensioning system, a travelling mechanism and the like of a tracked vehicle are separately designed and installed, so that the vehicle is easy to become complex in structure, complex to install, poor in reliability, time-consuming and labor-consuming to maintain and the like. Therefore, how to organically integrate the parts together by means of the swing arm on the basis of reducing the use of parts as much as possible and have better performances of tensioning, suspension damping and the like is one of research hotspots and difficulties in the field.
