Abstract

The utility model relates to a five-cylinder diesel crankshaft, aiming to solving the best power problem for a light vehicle and an agricultural vehicle. The utility model is characterized in that five cranks 2 are arranged on a crankshaft 1; a balance body 3 is arranged opposite to each crank. The five-cylinder diesel with the crankshaft 1 as one part is the best power of the light vehicle or the agricultural vehicle.

Description

Five cylinder diesel bent axles

The utility model relates to a kind of I. C. engine crankshaft, a kind of specifically five cylinder diesel bent axles.

The cylinder body number average of internal-combustion engine was that this is easier to make the internal combustion engine operation balance because of its technical ratio and produces with single or even numbers appearance in the past.The internal-combustion engine that occurs with cylinder numbers such as five, seven does not still have finding at home, does not have Chinese patent application through looking into yet.Because city's field boundary expanding economy, rural economy and urban and suburban roads enlarge rapidly, city's field boundary also is on the turn to the requirement of Light-duty Vehicle, agricultural vehicle, is power character and the travelling comfort proposition new demand of user to vehicle on the one hand, is that national policy (as emission standard) proposes new demand to internal-combustion engine on the one hand.Therefore, for adapting to the field boundary requirement of this city, five cylinder diesels are complied with situation and are given birth to.Five cylinder diesel bent axles as one of critical piece of five cylinder diesels have also just had new design, become a kind of new bent axle.

The purpose of this utility model provides a kind of bent axle of five cylinder diesels, for Light-duty Vehicle, this segmentation city field boundary of agricultural vehicle provide the parts on the novel internal combustion mechanomotive force that meets every requirement fully.

Realize that the technical solution of the utility model is such: five cylinder diesel bent axles, improve innovation by four cylinders or six-cylinder diesel engine bent axle and form.Five crank throws 2 are arranged on the bent axle 1, be provided with balanced body 3 on the opposite of each crank throw.These balanced body adopt the complete equilibrium method, through calculating, designing; Five crank throws 2 on the bent axle 1 are distributed in different positions, promptly do not have the identical crank throw of distribution angle 2 on the vertical center line of bent axle, distribution angle refers to the circumference angle.Other structure on this bent axle is identical with existing four cylinders or six-cylinder diesel engine bent axle with requirement, as oil leab being arranged, supporting spindle, end output shaft or the like on it.Five cylinder diesel bent axles are modified model bent axles of existing bent axle.

The beneficial effects of the utility model are: the balance of bent axle has been carried out well-designed, calculating, adopted the complete equilibrium method, disposed suitable balancer weight, made the balance of complete machine reach effect preferably; Five cylinder diesels can satisfy the power requirement of city's field boundary to this class comprehensively, thereby the city's field boundary that has also embodied this bent axle is worth.

Below in conjunction with accompanying drawing, the embodiment of five cylinder diesel bent axles is done comparatively detailed explanation.

Fig. 1 is the structural perspective of five cylinder diesel bent axles.

Embodiment: five cylinder diesel bent axles, improve innovation by four cylinders or six-cylinder diesel engine bent axle and form.Five crank throws 2 are arranged on the bent axle 1, be provided with balanced body 3 on the opposite of each crank throw.These balanced body adopt the complete equilibrium method, through calculating, designing; Five crank throws 2 on the bent axle 1 are distributed in different positions, promptly do not have the identical crank throw of distribution angle 2 on the vertical center line of bent axle, distribution angle refers to the circumference angle.Other structure on this bent axle is identical with existing four cylinders or six-cylinder diesel engine bent axle with requirement, as oil leab being arranged, supporting spindle, end output shaft or the like on it.Five cylinder diesel bent axles are modified model bent axles of existing bent axle.

Claims

1, five cylinder diesel bent axles improve innovation by four cylinders or six-cylinder diesel engine bent axle and form, and it is characterized in that: five crank throws (2) are arranged on the bent axle (1), be provided with balanced body (3) at the opposite of each crank throw the other end.

2, five cylinder diesel bent axles according to claim 1 is characterized in that: five crank throws (2) on the bent axle (1) are distributed in different positions, promptly do not have an identical crank throw of distribution angle (2) on the vertical center line of bent axle.

3, five cylinder diesel bent axles according to claim 1 is characterized in that: other structure on this bent axle is identical with existing four cylinders or six-cylinder diesel engine bent axle with requirement, as oil leab being arranged, supporting spindle, end output shaft or the like on it.
