specific Embodiment

[0099] A 300kW crawler bulldozer has a mass of 50,000kg (excluding the mass of the scarifier), and its working environment temperature is between -40°C and 50°C.

[0100] 1. Design of slider guide rail mechanism

[0101] The upper and lower distances between the fixed slider and the guide rail are determined as follows:

[0102] 1.1. Determination of the vertical distance between the fixed slider and the bottom of the guide rail

[0103] The maximum design load of the track roller device is the working condition that only one pair of track roller devices bear the weight of the whole machine when passing obstacles. Therefore, it can be considered that under the ultimate load, the viscoelastic shock absorber reaches the maximum compression deformation. At this time, the vertical distance between the roller device and the car body is the basis for determining the vertical distance between the fixed slider and the bottom of the guide rail. At this time, the vertical distance bet...

Abstract

The invention belongs to a crawler type engineering vehicle thrust wheel device, in particular to a sliding type damping buffering thrust wheel device which solves the problem that the prior crawler type engineering vehicle thrust wheel device uses rigid connections, so a traveling mechanism produces dramatic vibration and impact easily, thereby influencing the service life of vehicle components and the comfort of driving and also being likely to cause the hazard of the digression of the crawler . The sliding type damping buffering thrust wheel device comprises a thrust wheel, a support frame and a suspension mechanism. A viscoelastic vibration damper is installed between the support frame and a trolley frame. The suspension mechanism is a slide rod guideway type structure. The sliding type damping buffering thrust wheel device has the beneficial effects as follows: 1. the sliding type damping buffering thrust wheel device ensures that contact area of the crawler when traveling and reduces the vibration and the impact, the service life can be 8,000 to 10,000 hours, and the vehicle can obtain large traction and avoids the hazard of the digression of the crawler; 2. the sliding type damping buffering thrust wheel device improves the comfort for driving the vehicle, and the vibration measured at the position of a driving seat is reduced by 7 percent; and 3. the vehicle operation productivity is increased by 10 percent.

Description

technical field [0001] The invention belongs to the technical field of track roller devices for engineering vehicles, and in particular relates to a sliding type damping buffer roller device. Background technique [0002] Large and ultra-large modern engineering vehicles have the advantages of high operating productivity and low unit earthwork construction cost, but the increase of the model will inevitably cause more and more severe vibration and impact. With the increasingly stringent international environmental protection regulations and the fierce competition in international trade, many countries in the world have taken the vibration and noise indicators of construction machinery as technical barriers to restrict imports. For traditional crawler-type construction vehicles, the supporting wheels of the traveling system are rigidly connected, that is, the supporting wheel shaft is directly rigidly connected with the platform frame, and the platform frame and supporting wh...
