Brush chipper and methods of operating same

An improved brush cutter having an upper feed control member with stop, forward, neutral, and reverse positions also has a lower feed stop member with selectable sensitivity. Another aspect of the invention is to predict the feed roller shutoff point according to the rate of engine deceleration. According to another aspect, when the feed rollers stop feeding material into the cutters, to overcome drag on the cutters, a controller stops the feed rollers and then reverses them for a short time, and then reverses the rollers again if the problem is still present. To prevent jamming, a pressure switch senses when oil in a hydraulic motor system for rotating the feed rollers is too high and the controller momentarily reverses the feed rollers and then causes them to go forward, a cycle which can occur several times until the feed rollers are no longer stalled. By another aspect of the invention, the controller senses characteristics of the brush cutter and chooses an operating system based on the characteristics sensed. The controller can also sense if the brush chipper has not been used for a predetermined period of time and automatically reduce the idle speed of the engine until the brush chipper is used again, and then automatically return the engine to a normal idle speed before the feed rollers will pull brush into the brush chipper.

Amphibious vehicle

The amphibious vehicle is a motorized vehicle capable of travel on land as well as in the water. The amphibious vehicle has a boat-like hull, and a caterpillar track assembly mounted along each side by hinges. The tracks are arranged so that they can be rotated between a lowered position, where they support the amphibious vehicle and provide traction and propulsion during land operation, and a raised position, where they rest vertically on or above the hull's deck during marine operation. With the caterpillar track assemblies in the raised position, stowed on the hull's deck, the caterpillar track assemblies are fully removed from the water to improve performance and maneuverability. Additionally, with the tracks in their upright position the overall width of the amphibious vehicle is narrowed to facilitate trailering. The tracks employ hydraulic motors in a direct drive configuration for propulsion, reducing weight and complexity of the tracks.

Vehicular drive system

ActiveUS20050139401A1Minimize loss in driving forceLoss of driving forceGearboxesMechanical actuated clutchesVariatorPower transmission
In a vehicular drive system for a hybrid vehicle, in which driving forces of an engine and a motor are transmitted through a power transmission mechanism to driven wheels, a common oil stored in a transmission case and a motor case is used for lubricating the power transmission mechanism and the motor. During travel by means of an engine, when a synchromesh mechanism operated by a shift fork isolates the motor from the power transmission mechanism, an oil return hole blocking rod, provided in the shift fork, blocks an oil return hole providing communication between the motor case and the transmission case, thereby preventing oil in the motor case from flowing into the transmission case, to lower oil level in the transmission case. Thus, during travel of the hybrid vehicle, driving force loss due to motor drag resistance and oil stirring resistance is minimized.

Pressure injection method for integral forming of non-pneumatic tire

InactiveCN105599214ASimple processSpecial craftTyresDynamic balanceEngineering
The invention provides a pressure injection method for integral forming of a non-pneumatic tire. The method includes the following steps that firstly, configured raw materials for manufacturing the non-pneumatic tire are placed into a material storage box and are evenly stirred; secondly, the temperature of a pre-heating pressure injection machine is raised to 180-190 DEG C; thirdly, pressure of the pre-heating pressure injection machine is increased to 50-60 Pa; fourthly, the material inflow speed is adjusted to 10-20 m / s; fifthly, the pressure holding time is adjusted to 2-3 min; sixthly, the raw materials for manufacturing the non-pneumatic tire in the first step are injected into the pressure injection machine, and operation is started according to a preset mode; seventhly, after mold assembly, injection, hot melting, cooling and mold disassembly are sequentially performed, the non-pneumatic tire is obtained. The technology is simple, multi-time machining is not needed, one-time forming is achieved, operation is convenient, and cost is low; the obtained non-pneumatic tire is uniform and reasonable in structure and is not divided into an inner tire and an outer tire, friction force and resistance between the inner tire and the outer tire are eliminated, dynamic balance is good, and the non-pneumatic tire is resistant to abrasion and rolling and durable.
