Problems solved by technology

However, after many domestically produced high-horsepower tractors are equipped with cabs, the noise around the driver's ears is not only not reduced, but it is much larger than when there is no cab.

Abstract

The invention discloses a buffer vibration-reducing type high-powered tractor and an assembling method thereof. The tractor comprises a machine body chassis and a cab base plate. A primary vibration-reducing device, a secondary vibration-reducing device and a third-stage vibration-reducing device are arranged between the machine body chassis and the cab base plate. The assembling method comprises a step (a) of clamping the high-powered tractor; a step (b) of clearing the machine body chassis and the cab base plate; a step (c) of filling a protective pad; a step (4) of assembling the primary vibration-reducing device; a step (e) of testing vibration-reducing work of the primary vibration-reducing device; a step (f) of assembling the third-stage vibration-reducing device; a step (g) of testing vibration-reducing work of the third-stage vibration-reducing device; a step (h) of assembling the secondary vibration-reducing device; and a step (i) of testing vibration-reducing work of the third-stage vibration-reducing device. The primary vibration-reducing device, the secondary vibration-reducing device and the third-stage vibration-reducing device interact to reduce vibration, vibration excitation between the chassis and the cab base plate is weakened, cab vibration is reduced, and noise in a cab is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of high-horsepower tractors, and in particular relates to a shock-absorbing high-horsepower tractor and an assembly method thereof. Background technique [0002] High-horsepower tractors generally refer to tractors with a power of more than 100 horsepower. As the market demand for high-power increases, the lower limit of the power coverage of high-horsepower tractors has gradually increased to 125 horsepower, and they are widely used in agricultural production. [0003] When the high-horsepower tractor is parked in place and the engine is running at a speed of 2000r / min with no load (hereinafter referred to as static), the ear noise is 97.5dB(A), which is the noise radiated by the vibration of the cab wall caused by the engine. The vibration of the cab depends on the vibration source, the transmission path and the dynamic characteristics of the cab itself. The vibration source of the cab is mainly the engin...
