The invention discloses a hydrostatic high-drive bulldozer comprising an engine, a rack, crawlers, a start switch, an electric handle, a bucket, walking frames, an operating cylinder, travel motors, a fan, a fan motor and a control system. The operating cylinder is used for driving the bucket to rise and fall. The hydrostatic high-drive bulldozer also comprises a hydraulic driving system comprising two sets of variable displacement piston pumps connected in parallel, two sets of travel motors, a driving controller and a control handle; the power output end of each travel motor is fixedly connected to a crawler driving wheel installed on the rack, and each walking frame is provided with a driven crawler wheel; the crawlers installed on the crawler driving wheel and the driven crawler wheel form a triangle; the hydrostatic high-drive bulldozer is easy to operate through working pumps connected in parallel, the variable displacement piston pumps and fan pumps, and at the same time the crawler driving wheels are installed on the rack, and separated from the walking frames, so that impact load directly delivered to the crawler driving wheels from ground is eliminated; the service life of the variable displacement piston pumps is prolonged effectively, and the driving comfort of drivers is improved.
Description
technical field [0001] The invention relates to the technical field of bulldozers, in particular to a hydrostatic high-drive bulldozer. Background technique [0002] A bulldozer is an engineering vehicle with a large metal shovel installed in the front. When in use, the shovel is lowered to shovel forward and push mud, sand and stones. The position and angle of the shovel can be adjusted to complete digging, The work of earth moving and unloading has the characteristics of flexible operation, convenient rotation, small required working surface and fast driving speed. It is mainly suitable for shallow excavation and short transportation of the first to third types of soil, such as site clearing or leveling, excavation of foundation pits with small depths and backfilling, pushing and building subgrades with small heights, etc. [0003] In recent years, due to the cumbersome operation of bulldozers and poor flexibility, the operators have worked extremely hard, and the energy ...
