Description
Technical field:
The present invention relates to mechanical engineering technical field, is a kind of power transmission system of self-propelled mowing car specifically, adopts half wide V-belt formula infinitely variable speeds dynamic transfer system
Background technology:
The dynamic transfer system of grass-cutting vehicle generally is divided into the two large divisions now, and the one, running gear, the 2nd, mowing system.Running gear is divided into step speed change and infinitely variable speeds, and step speed change divides single-stage and multistage; Infinitely variable speeds is divided into hydraulic pressure, electric power and machinery, and mechanical stepless speed change is divided into roller square position formula, belt-type or the like, and the belt-type infinitely variable speeds has divided multiple again.The power transmission mowing system that drives cutter is divided into gear drive, friction-type belt transmission and cog belt transmission.
Existing grass-cutting vehicle major part is the hydraulic-driven walking, and the V-belt drives cutter and rotates in the same way, and the side goes out grass.The hydraulic-driven benefit is handiness, but efficient is very low; It is that the V-belt is incompatible oppositely tortuous that the V-belt directly drives the cutter shortcoming, and a plurality of cutter must be oppositely tortuous, and service life is short; The side goes out grass makes the lawn can not single treatment clean, and the lawn can stay the grass bits of cutting off, and just must increase a transmission blower fan etc. if will collect the grass bits, otherwise it is bad to collect careless effect, and so not only complexity but also efficient are low.
Summary of the invention:
The objective of the invention is to overcome the deficiency of above-mentioned prior art, and a kind of power transmission system of self-propelled mowing car is provided, solve mainly that existing grass-cutting vehicle efficient is low, the life-span is short, complex structure and collect problem such as careless weak effect.
In order to achieve the above object, the present invention is achieved in that power transmission system of self-propelled mowing car, it comprises engine-driven running gear of vertical shaft and mowing system, its special character is duplex belt pulley of vertical shaft motor driven, race drives driving mechanism above the duplex belt pulley, below a pulley groove drive mowing mechanism; The belt pulley that drives driving mechanism drives the infinitely variable speeds wheel by speed-governing belt, the infinitely variable speeds wheel has two equiform races, one is input race connection engine belt pulley, another is the big belt pulley on the output race connection drive axle, big belt pulley is coaxial to be fixedly connected with a minor sprocket, minor sprocket is connected with hinge wheel on the drive axle by chain and tightener sprocket, hinge wheel, main reduction pinion teeth, the commutation drive bevel gear, clutch collar is coaxial by dynamic bevel gear with commutation, clutch collar is in the commutation drive bevel gear and between commutating by dynamic bevel gear, when clutch collar and commutation drive bevel gear when engagement to overtake, when being meshed by dynamic bevel gear with commutation, clutch collar travels backward, when not meshing with two is neutral gear, if the back moves forward and backward by commutating, just power has been passed to main reduction pinion teeth, main reduction pinion teeth drives main deceleration gear wheel, main deceleration gear wheel is a gear not only but also be differential casing, and main deceleration gear wheel drives two semiaxis by differential gear and drives two tires on the drive wheels rotations; Drive the belt pulley of the belt pulley of mowing mechanism by V band and regulating wheel driving, belt pulley and left cutter and following profile of tooth belt wheel are installed on the same axle, this axle rotates with belt pulley, left cutter and profile of tooth belt wheel, profile of tooth belt wheel on the cutter installation shaft of a left side passes to the profile of tooth belt wheel that is positioned on the right cutter installation shaft by cog belt and regulating wheel, the profile of tooth belt wheel rotates with installation shaft and right cutter, the rotation direction of two cutteves is opposite, and the position is mutually an angle of 90 degrees.
Power transmission system of self-propelled mowing car of the present invention, setover in the center of its described drive axle, to give careless passage slot milling; Its described cutter drives by 4 identical profile of tooth belt wheel and cog belts of the number of teeth, and the cog belt wheel that drives cutter has especially big cornerite; Its described infinitely variable speeds wheel floats, and the tensioning of speed belt does not need regulating wheel.
Compared with the prior art power transmission system of self-propelled mowing car of the present invention has outstanding substantive distinguishing features and marked improvement: 1, adopt half wide V-belt formula infinitely variable speeds dynamic transfer system, in handiness, improved efficient again, when simplifying the internal structure of an organization, increased reliability again, and its excellent performance; 2, drive axle is seriously setovered, and with the space in the middle of abdicating to grass outlet, makes the grass bits of cutting off can directly be discharged in the collection straw bag of back; 3, cutter drives by 4 identical profile of tooth belt wheel and cog belts of the number of teeth, and the cog belt wheel that drives cutter has especially big cornerite, makes running reliable, is difficult for jumping tooth; 4, system can manually control speed, can control by foot-propelled again, has excellent handiness, has improved convenience than step speed change, has improved efficient than hydraulic stepless speed change, and is energy-conservation reliable.
